Device for ventilating and extracting air from rooms has controller that derives absolute humidity from sensor measurement data, compares it, and activates fan if absolute air humidity in surroundings in less than in room
The device has at least one air feed opening (2), at least one extraction opening (3) and at least one associated fan (4) controlled by a controller (6) with inputs for internal and external sensors (9,10) of at least temperature and humidity of the ambient air. The controller derives absolute humidity from the sensor measurement data, compares it and activates the fan if the absolute air humidity in the surroundings in less than in the room (1).
